Omron F3SJ-A0920N55 Safety Light Curtain
Omron F3SJ-A0920N55 is a Safety Light Curtain configured for leg and body protection across a 920 mm protective height. Its optical field contains 19 beam axes arranged with a 50 mm beam gap and uses an 870 nm infrared LED light source. The sensing range extends from 0.2 to 9 m, while the unit operates from a 24 VDC supply. An M12 8-pin connector and NPN transistor outputs provide the electrical interface with compatible safety equipment. Within the F3SJ Series, the F3SJ-A0920N55 provides extended body-level protection.

The Omron F3SJ-A0920N55 Safety Light Curtain provides leg and body protection across a 920 mm protective height. Its optical field consists of 19 beam axes arranged with a 50 mm beam gap and uses an 870 nm infrared LED light source. The sensing range extends from 0.2 to 9 m, while the unit operates from a 24 VDC supply. An M12 8-pin connector provides the electrical interface. Two NPN transistor outputs support maximum load currents of 300 mA each. Output short-circuit and power-supply reverse-polarity protection are specified, while the enclosure carries an IP65 rating.
When selecting the F3SJ-A0920N55, the 50 mm beam spacing, 920 mm protective height, NPN output format, M12 connection, and sensing distance should be considered together. These parameters define a leg and body protection field rather than finer hand or finger detection. Related F3SJ models use closer beam spacing when the required protection category changes. For an NPN hand and arm configuration with a 25 mm beam gap and an 870 mm protective height, see Omron F3SJ-A0870N30.
